WireGuard on mobile - battery drain? Tried & tested numbers

[Tap]

yo so I've been messing around with wireguard on my android and iPhone lately. honestly, was kinda worried about battery life cuz I read some horror stories but here's the deal. ran a test with my old pixel 4a and an iPhone 12. had wireguard connected nonstop for 3 hours while doing normal stuff - browsing, streaming, social media. on android, battery dipped from 100 to 87%, and on iPhone, it was from 100 down to 83%. not perfect but not bad either. what's interesting is the speeds. on android, I was getting around 55 Mbps down, 10 Mbps up. on iPhone, about 50 Mbps down, 9 up. both devices using the same server, same protocol, just wireguard. so yeah, it's faster than openvpn or IKEv2 I tried before. I even tested it on a 5G connection, and it held up well. honestly, I was kinda expecting way worse battery drain but this was pretty manageable. only downside is that on the most recent update, I noticed some quick battery drops when the screen was off but it stabilized after I toggled it off/on. still, if u wanna go with wireguard for mobile, u might wanna keep an eye on battery stats for ur specific device but overall, I'm pretty impressed with the speed & battery impact. kinda surprised it's this light tbh

yep exactly, but imo depends a lot on the device and background apps. i had similar tests but on some phones, wireguard kept battery draining even when idle. ymmv, just gotta keep an eye on

 

[Amplify]

just my 2 cents, but yeah, ymmv for sure. some phones or even specific apps might keep wireguard running in the background longer than others, so u gotta test ur own setup. don't forget to check battery stats regularly to see if it's acting weird.

 

[Haze]

i get what you're saying but I think it really depends on the VPN config and how the device handles background processes sometimes even with similar setups, I saw my old phone drain faster with wireguard than newer ones so gotta keep that in mind.

thanks for the tips, y'all. yeah, background apps and device tweaks can really mess with battery. I agree, gotta test ur own setup and configs, no one-size-fits-all. u also gotta keep an eye on those apps running in the background

 

[Pyre]

I disagree - I've run WireGuard on my phone for months and didn't notice any significant battery drain, so I think it might depend on how often you're connected or the device itself.

 

[Savory]

man disagree, wireguard on my phone barely drains battery either. maybe your test wasn't thorough or your phone's settings are different lol.

 

[Strategy]

bruh, you mean "Tried & tested numbers" as in a solid sample size or just random guesses? lol, that sounds kinda vague for real data

 

[Stream]

careful with taking those numbers at face value fam, seems like a lot of variables can skew the results. I've used WireGuard on my phone for ages and barely seen any drain, so idk where these "tested numbers" even come from lol

 

[Shunt]

spot on. one thing that helped me reduce battery drain with WireGuard is to tweak the kill switch settings and disable background activity for the app. sometimes small config changes make a big difference.

 

[Outlier]

around 15% battery drain over 8 hours for me with WireGuard, but I always disable it when not in use. also, turning off the persistent keep-alive setting helped save more juice. small tweaks, big difference.

 

[Empathy]

just my 2 cents, I ran some tests myself and saw about 10-12% battery drain over 8 hours with WireGuard active, but that was with keep-alive ping set to 25 seconds. dropping it to 60 seconds cut drain down to around

 

[Logic]

Honestly I think the kill switch and background settings only matter if you're really trying to squeeze every bit of juice. most of the drain comes from the VPN doing its thing, not the app itself. anyone noticed if switching protocols makes a difference?
